Crosswind Landing Technique

Crosswind landings use the crab method, the wing-low method, or a crab held until the flare and converted to wing-low at touchdown.

The Crab Method From Downwind to Flare

The crab method points the nose into the wind and keeps the wings level while the aircraft flies slightly sideways relative to its own heading, so the track over the ground stays on the centreline even though the aeroplane is not aligned with it.

On downwind the aircraft crabs one way, on base the same wind is almost a direct headwind so the crab is small, and on final the crab points into the wind while the ground track stays on the extended centreline. Wind 20 kt 27 Downwind Crab 14° left of track Base Near-direct headwind, crab 2° Final Crab 12° into wind Track stays on the extended centreline
One wind, three different crab angles. The correction is largest when the wind is most across the flight path and shrinks to almost nothing when the aircraft turns into it on base.

What makes crab comfortable is that nothing is cross-controlled. The aircraft stays coordinated, the ball stays centred, passengers feel a normal approach, and the pilot's only task is choosing the angle. That angle changes at every turn in the pattern, which is what the diagram above shows: the same 20-knot wind demands 14 degrees on downwind, almost nothing on base where it has become a near-direct headwind, and 12 degrees on final.

Finding the angle is trial and error in practice. Pick a starting correction, hold the heading, and watch the runway. If the centreline drifts across the windscreen, the correction is wrong and the direction of drift tells you which way to adjust. Experienced pilots converge in two or three corrections; the underlying arithmetic is the same crab calculation used for navigation on the drift correction page.

The weakness arrives at touchdown, and it is a real one. Landing while still crabbed puts the wheels down pointing one way while the aircraft travels another, which side-loads the gear hard. The pilot must therefore kick the nose straight with rudder in the last second or two before contact, a manoeuvre with a narrow window, since doing it early lets the aircraft drift before it lands.

The Wing-Low Method and Its Control Inputs

The wing-low method lowers the upwind wing with aileron and holds the nose straight with opposite rudder, so the aircraft is aligned with the runway from well before touchdown and needs no last-moment change.

Right panel shows the rudder pedals with the left pedal pushed forward, opposite to the aileron input. The two together hold the aircraft aligned with the runway while the upwind wing stays down.

Phase Aileron Rudder What is happening
Established on final Small, into wind Opposite, small Enough to stop drift, no more
Over the threshold Increasing into wind Increasing opposite Nose comes onto the centreline
In the flare Held or increased Holding nose straight Speed decays, controls need more travel
At touchdown Full into wind developing As required Upwind main wheel touches first
Rollout Progressing to full Steering the centreline Aileron increases as speed falls

Two things about the table catch students out. The inputs are not fixed, both grow as airspeed decays, because a control surface at 55 knots does less than the same surface at 75. And the aileron keeps increasing after the wheels are down, all the way to full deflection at taxi speed. The price of the method is a cross-controlled configuration held continuously, and a stall speed slightly higher than wings-level because part of the lift vector is being spent sideways.

Student Errors That Show Up on Every Checkride

Four errors account for most unsatisfactory crosswind landings, and three of the four happen after the wheels are already on the ground.

  1. Correcting too late

    Drift left uncorrected until the flare forces a large, rushed input at the worst moment. Start the correction on final, where a small input holds the centreline and there is time to trim it.

  2. Over-controlling the rudder

    Chasing the nose with large alternating rudder inputs makes the aircraft weave and hides whether the drift is actually cancelled. Set a rudder position, hold it, and adjust in small increments.

  3. Drifting after touchdown

    Relaxing once the wheels are down lets the aircraft weathervane and slide sideways while still fast enough to matter. The landing is not over until taxi speed.

  4. Releasing aileron too early

    Aileron must increase toward full deflection as the rollout slows, because the controls lose authority as speed decays. Centring the yoke after touchdown lets the upwind wing rise.

The pattern behind all four is treating touchdown as the end of the landing. The aircraft is still flying, still generating lift, and still exposed to the same wind for the whole rollout, and the controls need more input rather than less as it slows. The takeoff case runs the same logic in reverse and is covered on the departure technique page.

Matching the Method to the Aircraft

Aircraft geometry decides the method: anything with limited bank clearance crabs, and anything with a rearward centre of gravity uses wing-low.

Light GA

Cessna, Piper, Cirrus

Wing-low into touchdown is the standard, because short flexible gear tolerates no side load and the low wing loading makes the sideslip easy to hold. Most training syllabi teach crab on final converting to wing-low over the threshold.

Airliners

Narrow and wide-body

Crab is held well into the flare and removed with rudder in the last seconds, a technique called de-crab. Long flexible gear absorbs a few degrees of residual crab, and engine pods under a low wing limit how far the aircraft can be banked before a nacelle strikes.

Tailwheel

Cub, Champ, Decathlon

Wing-low is close to mandatory, and the aircraft must be flown until it is tied down. The centre of gravity behind the main wheels makes any residual side load want to swap ends, so aileron goes to full into wind during the rollout without exception.

Whatever the aircraft, the decision starts with a number rather than a technique. Work out the component on the runway crosswind calculator and compare it against the manufacturer's demonstrated figure before deciding the approach is worth flying at all. When the calculator is not to hand, the clock-code estimate is close enough for a runway choice.

Landing Technique Questions

Which crosswind landing method do airlines use?

Airlines fly a crab down final and remove it with rudder in the last few seconds before touchdown, a technique known as de-crabbing. Wing-low is limited by geometry: banking a low-wing jet far enough to cancel a strong crosswind risks striking an engine nacelle or a wingtip. Long, flexible main gear is designed to absorb a few degrees of residual crab, so a small amount at touchdown is accepted rather than eliminated.

What happens if you land in a crab without correcting?

The wheels touch while pointing off the direction of travel, which side-loads the landing gear and jerks the aircraft into alignment. In a light aircraft this produces a violent swerve toward the direction the nose was pointing, and it can collapse a gear leg or roll a tyre off its rim. Airliners tolerate a few degrees by design; light aircraft do not, which is why light training aircraft are taught wing-low.

How much aileron is needed on rollout after touchdown?

Aileron should progress toward full deflection into the wind as the aircraft slows. This is counterintuitive to students, who expect to relax the controls after landing. Control effectiveness falls with airspeed, so holding the same input as speed decays means holding progressively less actual authority. Full aileron by the time you reach taxi speed is the standard target.

Is the wing-low method harder to learn than the crab method?

Wing-low is harder initially because it requires cross-controlled inputs that every earlier lesson has discouraged. Students spend the whole course learning coordinated flight, then have to deliberately uncoordinate on short final. Crab feels natural by comparison, since the aircraft stays coordinated throughout. The difficulty reverses at touchdown, where crab requires precise timing and wing-low requires nothing new at all.

Do tailwheel aircraft need a different technique?

Tailwheel aircraft use the same wing-low method but demand it be held far longer and more precisely. With the centre of gravity behind the main wheels, any sideways motion at touchdown starts a swing that gets worse rather than damping out. The aircraft must be flown continuously until it is stopped, with aileron progressing to full into wind throughout the rollout.
